1 Terminodour Odour control for the 21st Century

Terminodour and the Environment The Terminodour Process Traditional odour control systems consume a significant amount of energy and, in many cases, utilise large quantities of chemical, water and media requiring regular and expensive disposal. TerminodourTM offers a low carbon footprint solution for odour abatement as power consumption is a fraction of traditional systems and TerminodourTM does not require any chemicals, water or media. TerminodourTM provides cost effective proven odour control in an environmentally beneficial manner. The TerminodourTM process combines ventilation and ionisation technology to provide efficient air distribution with maximum oxidation capacity to deliver highly effective odour control within a building or any enclosed space. The TerminodourTM process encompasses a holistic approach to effective odour abatement and, where people are present, ensures good internal air quality. Terminodour Background The first TerminodourTM system was installed in the UK in 1996 since then the process, through a programme of research and development, has become one of the most exciting developments in the field of odour abatement. Extensive process development has now resulted in a tried, tested and proven system that is providing our clients with cost effective odour control and improved air quality. Our references speak for themselves but we will happily provide you with contact details so you can check our credentials. Operation Most odour control systems extract odour from the point of source and feed via ductwork to an abatement system where the odours are either oxidised or absorbed before the treated air is emitted to the atmosphere. The TerminodourTM system does not extract the odour but actually oxidises the odour at the point of source using either the building superstructure or space beneath the Fresh air is drawn by a fan (3) into the TerminodourTM system via an external louvre (1) and is then filtered (2) to remove particles. The filtered air is then passed into the plasma reaction chamber (4) where the hydrogen and oxygen molecules are electrically charged in a 5:4 ratio (negative/ positive). The resulting ions are then distributed around the building according to the location and severity of odour emission points within the building or chamber. The ductwork system design is an extremely important part of the process and is a critical element of the design to ensure that ions are distributed at the right quantity and rate to meet the level of odour generation at specific points.

3 The heart of the Terminodour TM process is the Terminodour TM air handling unit (AHU) that contains the principal system components; these include the inlet filtration section, fan(s), plasma reaction chamber, ionising modules etc. Terminodour TM Reaction Terminodour TM has the capacity to oxidise all organic doours, efficiency is a function of contact time and the length of the molecular structure of the molecule to be oxidised. Hydrogen sulphide is the trace indicator gas found in wastewater and given sufficient contact time with the ions produced by the Terminodour TM unit will be oxidised to a benign, non-toxic sulphate ion. Terminodour TM Performance CSO Technik can provide performance guarantees for odour abatement efficiency on both new build and retrofit applications. Performance efficiency varies according to a number of parameters however we typically offer odour reductions of 80-95% within a building and up to 99% for storage tank or wet well applications. Terminodour TM Applications Terminodour TM has been proven to be efficient in numerous applications including: Municipal wastewater Industrial wastewater GRP or FRP manufacture Food processing Terminodour TM Benefits at a Glance Cost effective odour abatement Combines odour abatement and ventilation in on package Low carbon footprint No chemicals, water or media disposal costs Instantly effective - no start up delay Can handle variable loadings Simple non specialist maintenace Reduces sulphide inspired corrosion Improves internal air quality ATEX rated Terminodour TM Heath and Safety CSO Technik have designed the Terminodour TM system specifically for treating odours in areas that may potentially have explosive gasses present such as wastewater treatment plants. The system has full ATEX certification. Although it is perfectly possible for ionisation equipment to produce ozone the Terminodour TM design ensures that any ozone produced is minimal and far below the occupational exposure level of 0.1ppm. Scope of Supply CSO Technik offer a complete turn-key service including: odour surveys, design, manufacture, supply, installation, commisioning, testing and after sales service. In addition to Terminodour TM we are able to offer a wide range of alternative odour control systems and ancillary products such as GRP covers.

6 Terminodour TM Combination Systems In certain applications, specifically where odour levels are very high, Terminodour TM may not be a stand alone solution however in combination with various scrubbing systems it can provide a lower cost solution by treating the high volume/low load odours with Terminodour TM but extracting the low volume/high load odours to a separate odour abatement scrubbing system. A typical application would be a sludge centrifuge building. This provides the following benefits: Smaller scrubbing system - lower capital and running costs Much lower power demand dye to lower pressure drops Reduced footprint Improved internal air quality Odour Abatement - Solutions Bio-trickling filter with polishing carbon filter for Dwr Cymru 2 No. carbon filter and emission stack for a styrene abatement plant CSO Technik believe that no single odour control system is suitable for every odour problem, consequently CSO Technik provides a full range of odour abatement solutions including the following: Biofilters Bioscrubbers Dry Chemical Scrubbers Wet Chemical Scrubbers Catalytic Iron Filters CSO Technik provide a complete turn key project service including supply and installation of ancillary equipment such as control panels, kiosks, ductwork, covers etc. Specialist Ventilation Systems CSO Technik provide specialist ventilation systems for the water, pharmaceutical and general industry, our expertise covers: Safe man entry systems Boiler make up air Dust extraction Staircase pressurization systems Investigation, testing and reporting on existing ventilation systems

7 Odour Abatement - Covers High security flat covers with non trip fixtures, double seals and bolted fixings with embedded nuts into GRP CSO Technik provide a wide range of GRP covers to suit most applications including rectangular tanks, circular tanks, channels, screw pump covers etc. Covers can be manufactured to suit a wide range of loadings according to need. Our high security range of covers have double seals and are guaranteed not to lift or separate from the structure. The covers are fixed using bolts and embedded nuts to ensure a high quality seal and that covers can be removed and replaced easily. The high security range is specifically for highly sensitive sites or where microbiological hazards are a concern. We can also offer a budget range of covers with a single seal arrangement where the benefits of the high security range are not a high priority and price is of paramount importance.
